About GCC for RISC OS

GCC for RISC OS is a complete, free and fully-featured compiler solution
for RISC OS based on the GNU Compiler Collection. It can compile C and C++
using modern standards and assemble ARM code. It also includes support for
RISC OS modules, and usage of the native RISC OS Shared C Library, or the
bundled Unix-compatibility library UnixLib as runtime library. It aims to be
feature complete above and beyond the commercial RISC OS Open Ltd’s C/C++
compiler suite.
